There are errors in last night's rolling boot.log:
Switching / to tmpfs...
Done
Processing /etc/init.d/rcS...
wc: invalid option -- 'm'
BusyBox v1.12.0 (2010-03-12 18:25:03 CET) multi-call binary
Usage: wc [OPTION]... [FILE]...
Print line, word, and byte counts for each FILE, and a total line if
more than one FILE is specified. With no FILE, read standard input.
Options:
-c Print the byte counts
-l Print the newline counts
-L Print the length of the longest line
-w Print the word counts
The same thing occurs 11 times in boot.log. So, I looked around and found that ...
/lib/libtaz.sh
/usr/libexec/tazpkg/search
/usr/libexec/tazpkg/upgrade
... contain the faulty "wc -m" statement.
